IN CALIFORNIA:
Bartlett Springs contains 67 mg/l calcium, 360 mg/l magnesium,
and 4.3 mg/l sodium. This unique spring water has been bottled
since 1869, and is reputed to have a laxative effect due to its
360 mg/l magnesium content. Vittel of France bought it and
bottled it under the name Vittel, but it failed in the
marketplace. It is rumored to be for sale complete with a new
bottling plant for $10 million. The laxative effect could be
removed by diluting it with low TDS water to give a magnesium
content of 90 mg/l. It is not currently bottled. Flow: 55 gallons
per minute.
Adobe Springs is in Stanislaus
County, California and contains 3.8 mg/l calcium, 110 mg/l
magnesium, and 6.4 mg/l sodium. There is no laxative effect.
Adobe Springs is family owned and
operated. Water is sold in bulk to bottlers. The taste is
commonly described as sweet. Flow: 142 gallons per minute.
